Patented June 1968. Serial No. i3fl88a To all wizoc-n it may concern:

Be it known that i, Nesson W minus, J12, s citizen of the siding New Yo l eity, in the coun j State of New York, have iiwentcd new and useful l iroven'icnts in Workii "-TOOlS; and .i do hereby do follovv'ing to he a full, clear, and 1 scription of the invention, such .l able others skilled in the art to which i pertains to n ks and. use the same.

My inv relates to certain new and useful improvements in storm-Wei of the kind wherein the outt b is cflected by means oi d sh :1

otonei undum or other like material, mounted upon a stumble shaftor spindle.

The main ob not or purpose of the :nvex

tion is to provide for the ready rein the disk from the shaft, Without tlu sity of shifting t lo situdinnll, also to in i for the eileotive in and cooliiig of t-ll' d its av-1 n the cutting opera i to is cleitring oi the liOli from debris. ins; out this purpose, I. have vmule up t'ie tool by assembling upon the t or indie a plurality of individual die 1 ill cert yer lslriina 'ns arranged side by side to form it composite ebrader, the indivii'luel elements huving peripheral contour appropriate to the character of the proposed cut or Z Erich ot the individual dislw or lain lOnS is promg, the inner surface of which fits the t or indie end which extends outwardly to the opposite periphery of the disk, so that the several individual. disks or loininetions may he rcndil' ng'iped over the shaftor spindle laterally vided with redial s may then be clamped together, and so that they may be either separately pr collectively removed and eplnced in like manner, The redial slots of the severii ind' *idual disss or inminations are pr disk e the slot of each dish is severed by e. s ortiou or its neighbor in the series 1 he redial slots, extending as they do to th periphery ofthe composite dish-s pe 7" l access 0 the Water-or other luhric 1 employed in ti cutting ,or olirz'iding operation, to t most surfaces of the lier, and by nerd i the tool and the stone from over-heating, but eilow the tool to be run at a higher speed than would otherwise be feasible. Theradisl slots also tend to clear the kerf from the debris of the cutting or sbrading operation, and may be kept clean; by a jetor jets of Water directed upon the tool should the debris, in any particular ihstance not clear itself readily fromthe slots as they rise out of the keri'. in the accompanying drawing, Figure 1, resents at side elevation of a stone-Workg tool embodying my improvements; Fig. represents a, sectional View thereof, partly plan.

Similar letters of referenceindicate similar psrts throughout the several views.

Referring to the drawing, 0 indicates the tool shaft or spindle, and a, .b, d, indicate a plurality of individual disks or leminations materiel, arranged side by side on the said shaft or spindle. Each of these individual disks or leminations is provided With a radial slot 7L, 'i, 1, respectively, which, at its inner end, is of a contour adapted to closely fit the shaft or spindle and whicl'i at its outer end extends to the disk edge or periphery.

As indicated, the outer peripheries of the several individual disks or lsminations may he of different contour, appropriate to the character of the out or kerf they are designed to make, and it is evident that any individual lamination or lsminations may be replaced by others of difi'erent contour or thickness, or that they may be removed and replaced in their entirety.

The individual disks or laminations are so disposed about the shaft 0 that the radial slot oi OZLCll of them is covered 'by a solid portion in order to sssist'in maintaining this relation- I ship they may-be cemented together along their ahuttin faces by acement Weaker than the cerborunoum or other material of'which tion from each other when it is desired to 'remove them from the sheft.

The means for releasably clamping the composite disk upon the shaft may e of any suitablekind. I in the drawing I have shown.

of its neighbor or neighbors in the series, and,

the leminetions are composed, so that the cement oints will not prevent their separaone appropriate form, consistin -ofcheek may be avoided by interposing between the 'ga s formed by the slotted cheek pieces f and the composite disk, washers g, of semielastic material, such as cork, paper or the like. 3

he invention is of particular advantage Where, as is frequently required in practice, a number of the composite disks are arranged at intervals upon a common shaft, or where in building up a composite forming or abrading tool such a number of individual laminations (either of the same or varying thickness, or of the same thickness and varying diameter) are-employed as to make the tool of relatively great length Wi respectto its diameter. In the latter cas 'fespecially, the

sections contri ute notably to the abrading capacity of the tool both because of the cooling and clearing function incident to their use, and because of'the efiicient lubrication throughout the entire length of the kerf.

Having thus described my invehtion, what I claim is:

1. A stone-working tool, consisting of a tool shaft, and a composite disk made up of a plurality of individual disks or laminations of abradin'g'material and arranged side by side on the shaft, said individual disks or laminations being provided with radial slots to permitthem to be readily assembled, re-

of the tool moved, or replaced, substantially as described. I

2. A stone-working tool, consisting of a tool shaft, and a composite disk made up of a I plurality of individual disks or laminations of abrading material and arranged side by side on the shaft, said individual disks or laminations being provided with radial slots to permit them to be readily assembled, removed, or replaced, the radial slot of each in.-

its neighbor; substantially as d ed.

3. A stone-Working tool, consisting of a tool shaft, and a composite disk made up of a plurality of individual disks orlaminations of abrading material-and arranged side by side on the shaft, said individual disks or laminations being provided with radial slots to permit them to be readily assembled, removed, or replaced, the radial slot of each individualdisk being opposite a solid portion of its neighbor, and said slots being disposed at equal distances apart so as to balance the tool; substan'tiallyas described.

In testimony whereof I aflix my signature, in presence of two witnesses.
